/*
 * The of_device *was* a kind of "base class" that was a superset of
 * struct device for use by devices attached to an OF node and probed
 * using OF properties.  However, the important bit of OF-style
 * probing, namely the device node pointer, has been moved into the
 * common struct device when CONFIG_OF is set to make OF-style probing
 * available to all bus types.  So now, just make of_device and
 * platform_device equivalent so that current of_platform bus users
 * can be transparently migrated over to using the platform bus.
 *
 * This line will go away once all references to of_device are removed
 * from the kernel.
